"It really allows you to be creative and literally extend the personality you had while alive in death," said James Norris, founder of DeadSocial. "It allows you to be able to say those final goodbyes."DeadSocial covers all the post-death social media options, scheduling public Facebook posts, tweets and even LinkedIn posts to go out after someone has died. The free service will publish the text, video or audio messages directly from that person's social media accounts, or it can send a series of scheduled messages in the future, say on an anniversary or a loved one's birthday. For now, all DeadSocial messages will be public, but the company plans to add support for private missives in the future.

"I don't think that somebody would continually be negative and troll from the afterlife," Norris said optimistically. "Nobody really wants to be remembered as a horrible person."
